Abstract

A pneumatic valve for controlling compressed air flow between a number of connections (2a-2e) on an injection molded plastic valve housing (1), comprises a valve slider (6) which is located inside a slider bore (5) in the housing, and pressurizing agent chambers (4a-4e) that are in contact with the outer connections. A pneumatic valve for controlling compressed air flow between a number of connections (2a-2e) on an injection molded plastic valve housing (1), comprises a valve slider (6) which is located inside a slider bore (5) in the housing, and pressurizing agent chambers (4a-4e) that are in contact with the outer connections. The chambers and the section of the slider bore near the chambers consist of a non-reinforced plastic, and are surrounded by reinforced plastic, which defines the external dimensions of the housing. The channel sections between the chambers and the connections are formed by the inside of the housing. The valve slider two outer sealing rings and the slider bore work together to seal the outer pressurizing agent chambers.
